Official Government of India census data (2001, 2011) gives numbers only for “Jains” as a whole, not separately for Digambar and Shwetambar. So there is no exact, official figure for only Digambar Jains.

However, from scholarly estimates and regional patterns:

• Total Jains in India (2011 Census): about 44.5 lakh (4.45 million)
• Digambar Jains are usually estimated to be around one‑third to about half of all Jains.

So, a reasonable broad estimate is:

> Around 15–25 lakh (1.5–2.5 million) Digambar Jains in India

Please remember: This is only an estimate, not an official census number, because the census does not distinguish between Digambar and Shwetambar separately.
